IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 216,020, dated J une 3,1879; application filed October 7, 1878.

To all whom it may concern.-

Be it known that I, ROBERT CAMPBELL, of Pittsburg, county of Alleghenyand State of Pennsylvania, have invented a new and useful Improvement inWashing-Machines and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

My invention relates to an improvement in washing-machines; and consistsof a tub or other water-holding device having a detachable perforatedchamber provided with standards, cross-rod, and lever, and a perforatedhead having concave faces, and provided with friction-rollers, all aswill be hereinafter fully described.

I To enable others skilled in the art to make and use my invention,Iwill proceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification,Figure 1 is a top view or plan of my improvement in washingmachines.Fig. 2 is a side elevation of the same, representing a portion of thetub broken away. Fig. 3 is a vertical section of the same. Fig. at is aperspective view of the sliding head.

In the accompanying drawings, A represents an ordinary wash-tub, inwhich is placed the detachable chamber B, which is a rectangular boxwithout top or bottom, having two of its sides perforated, as indicatedat c.

On two sides of the chamber B are two standards, D, which serve asbearings for the axis of the cross-bar e, in the center of which is anopening for the reception of the handlever f, the lower end of whichenters the sliding head g between the friction-rollers h.

The sliding head 9 has two of its faces made concave, as indicated at i,and has a series of openings, n, through it for the flow of waterthrough them.

The skilled mechanic will readily understand the construction of theseveral parts from the foregoing description and by reference to theaccompanying drawings. I will therefore proceed to describe theoperation, which is as follows: The chamber B, with its sliding head gand operating-lever], being arranged in the tub A as shown in theaccompanying drawings, a suitable quantity of water is put in the tub A,and a proper number of pieces of clothes to be washed is soaped andplaced in the compartments J and K, and a reciprocating motion impartedto the lever f, which will impart like motion to the-slidin g head g,forcing the clothes in the compartments J and K alternately against thesides I of the chamber B, which will force the water through theclothes, the perforations c and openings-n allowing the escape of thewater as it is forced through the clothes. The concave faces of thesliding head 9 will gradually turn the clothes so as to subject allparts of them to the forcing action of the sliding head 9.

The washin g-machine llereinbefo re described will. be efficient as awasher, and is simple in construction and not liable to become impaired,and for economy of labor in washing and cost of manufacture will meetthe expectation of the public.

Having thus described my improvement, What I claim as my invention, anddesire to secure by Letters Patent of the United States, 1s-- Awashing-machine consisting of a tub or other water-holding device, A,having a de tachable perforated chamber, B, provided with the standardsD D, cross-rod 0, and lever f, and a perforated head, g, having concavefaces 11 i, and provided with the friction-rollers h h, the severalparts constructed and arranged to operate substantially in the mannerherein shown and described.
